Abstract：
The flow angles for the final state particles with five kind of mass number(A=1,2,3,4 and 5-8)are determined for 1.2 A GeV An+Au collisions at the Bevalac by minimizing the azimuthal anisotropy in the center-of-mass coordinde systems where the z axis is rotated to various polar angles in the reaction plane.The study of the polar angle distributions for the final state particles with different mass in the systems with the z axis rotated to the flow angles indicates that the degree of concentration around the flow direction and the now value increase with increasing mass number of the particles.
